马坑铁矿赋存于石炭—二叠纪合火山岩的碳酸盐岩—碎屑岩建造的地层中,由辉绿岩和大理岩在火山气热液作用下形成含矽卡岩矿物组合的磁铁矿床。这类铁矿分布较广,是一个重要的矿床类型。为了探索这类矿床形成的温度、压力和介质环境,我们继《福建马坑矽卡岩分带的模拟实验》之后,采用马坑天然辉绿岩和大理岩作为试料,对该矿床形成的温度和压力进行了初步的实验研究。
The Mukeng iron deposit is hosted in carbonate-clastic rock formations of the Carboniferous-Permian volcanic rocks. Diabase and marble are formed by the combination of skarn minerals with volcanic gas hydrothermal fluids Magnetite deposit. Such iron ore is widely distributed, is an important deposit type. In order to explore the temperature, pressure and medium environment for the formation of these deposits, following the “Mocking Experiments of Macking Skarn Zonation in Fujian Province”, using natural kyanite and marble from MaKeng as a sample, Temperature and pressure conducted a preliminary experimental study.
